The way drm_of_find_possible_crtcs works is it tries to match the
remote-endpoint of the given node's various endpoints to all the
crtc's .port field. Thus we need to set drm_crtc.port to the output
port node of the underlying TCON.

The master bind function calls numerous drm functions which initialize
underlying structures. It also tries to bind the various components
of the display pipeline, some of which may add additional drm objects.
This patch adds proper cleanup functions in the error path of the
master bind function.
This requires the patch "drm/sun4i: Move drm_mode_config_cleanup call
to main driver", which splits out drm_mode_config_cleanup from
sun4i_framebuffer_free so we can call it separately.

The multiplication ratio for the PLL is required to be even due to the
use of a "by 2 pre-scaler". Currently we are likely to end up with an
odd multiplier even though there is an equivalent set of parameters with
an even multiplier.
For example, using the 324MHz bit rate with a reference clock of 24MHz
we end up with M = 27, N = 2 whereas the example in the PHY databook
gives M = 54, N = 4 for this bit rate and reference clock.
By walking down through the available multiplier instead of up we are
more likely to hit an even multiplier. With the above example we do now
get M = 54, N = 4 as given by the databook.
While doing this, change the loop limits to encode the actual limits on
the divisor, which are:
40MHz >= (pllref / N) >= 5MHz

Panel drivers may want to sent commands during the disable function, for

If link training at a link rate optimal for a particular

let the modeset complete and then retry. We save the link rate
value at which link training failed, update the link status property

the modeset on the current mode at lower link rate or if the current
mode gets pruned due to lower link constraints then, it will send a
hotplug uevent for userspace to handle it.

drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so no need to do this explicitly. Additionally it
uses debugfs_remove_recursive() to clean up the debugfs files,
so no need for adding fake drm_info_node entries.

drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so the drm_driver.debugfs_cleanup callback is not
needed.
